The first mold shell 1 and the second mold shell 12 absorb the water in the fluid slurry and perform preliminary drying and forming of the corundum furnace tube. After preliminary drying and forming, the operator can start the drive motor 11. The drive motor 11 drives the positive and negative threaded rods 7 to rotate, which drives the moving seat 8 to move outward at the same time, causing the first mold shell 1 and the second mold shell 12 to separate. The operator can then take out the corundum furnace tube located in the forming chamber 3, which saves the trouble of manual mold disassembly and improves the convenience of use. At the same time, the insert block 10 is inserted into the slot 9, and the operator can easily remove the first mold shell 1 and the second mold shell 12 for replacement. Disassembly is very convenient and improves the convenience of use. At the same time, when closing the mold, the operator only needs to start the drive motor 11 to rotate in the opposite direction, which drives the sealing gasket 4 to press tightly, which can achieve the sealing and mold closing operation, saving the trouble of manual mold closing and further improving the convenience of use.
